Abstract: The phimosis curing appliance according to the present invention allows a surplus prepuce in a pseudophimosis condition to be forcedly retracted toward a root of a human penis so that a glans of the penis can be surely kept in an exposed condition for a long time, and the appliance has a simplified structure suitable for standardization and mass production. The phimosis curing appliance 1 comprises an annulus waist holding belt 2 supportable on a human waist; a resiliently stretchable supporting belt 3 suspended from the waist holding belt to form a region through which the human penis extends; a resiliently stretchable traction belt 4 for connecting a rear portion 2b of the waist holding belt and the supporting belt; and a scrotum biasing zone 5 provided in a joint area of the supporting belt and the traction belt. An upper end portion of the supporting belt is connected to the waist holding belt and the scrotum biasing zone is drawn inward of the human groin by the traction belt.
